Description

[0002] With the continuous advancement of medical technology, interventional procedures have been widely used with the assistance of angiography machines. However, the X-ray radiation generated during these procedures poses a potential health threat to medical personnel. Therefore, medical radiation protection technology has emerged to reduce the radiation dose received by medical personnel during their work.

[0003] During angiography, doctors are exposed to X-rays for extended periods.

[0045] The radiation shielding curtain for the angiography machine head of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0046] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0047] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0048] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0049] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0050] like Figures 1-8As shown, the radiation shielding curtain for the angiography machine head includes: a fixed shell 1 that connects to the angiography machine head; a storage shell 2 that stores the lead plates 4 when retracted; a pulling device 3 that works with a storage rope 6 to pull the lead plates 4; a lead plate 4 that unfolds for radiation shielding; a suspension rope 5 that lifts and limits the relative position of adjacent lead plates 4 when the curtain is lowered; and a storage rope 6 that stores and holds the lead plates 4 together. The fixed shell 1 is fixedly connected to the storage shell 2 at its lower side to pull the lead plates 4 up and store them inside the storage shell 2. To facilitate the suspension rope 5 extending out of the fixed shell 1 and lifting the lead plates 4, the fixed shell 1 has a rope hole 11 at its bottom. The suspension rope 5 extends out of the rope hole 11, and multiple lead plates 4 are connected to the upper limit of the suspension rope 5. The storage rope 6 is used to conveniently limit the storage of the lead plates 4. The fixed housing 1 is internally connected to a pulling device 3. The bottom of the pulling device 3 has a pull rope hole 12. The lower end of the storage rope 6 extends to the bottom of the lowest lead plate 4, and the upper end of the storage rope 6 passes through the rope hole 11, wraps around the pulling device 3, and extends out along the pull rope hole 12. During the storage process, the lowest lead plate 4 is lifted, and the lowest lead plate 4 lifts the next lowest lead plate 4, thus lifting the lead plates 4 in sequence and realizing the storage function of the lead plates 4.

[0051] This allows the lead plate 4 to be stored inside the storage shell 2, and also allows multiple front plates 4 to be hung down and placed vertically in a single plane, thus achieving the function of radiation protection.

[0052] When the angiography machine head needs to rotate, the lead plate 4 can be stored inside the storage shell 2, so that the lead plate 4 will not fall off during the rotation of the angiography machine head, thus avoiding affecting the normal operation of the angiography machine head.

[0053] When the angiography machine head needs to be vertical, lead plates 4 can be dropped vertically to form a curtain-like structure that completely isolates the angiography machine head from radiation.

[0054] To ensure balanced lifting of the lead plate 4 and prevent gaps between adjacent plates due to inconsistent position and angle during lifting, thus affecting its radiation shielding effect, two symmetrical rope holes 11 are provided. The two ends of the lifting rope 5 extend from the rope holes 11 out of the fixing shell 1, and limit members 51 are fixedly connected to the rope 5. The upper side of the limit members 51 supports the lead plate 4. Limit members 5 are installed at the same height at the ends of the two ropes 5, thus providing balanced support for the lead plate 4 by providing limit members 51 on both sides.

[0055] To facilitate the lifting and storage of the lead plate 4 using the suspension rope 5 and storage rope 6, a connecting hole 41 is provided through the lead plate 4. The suspension rope 5 and storage rope 6 pass through the connecting hole 41. A limiting member 51 is fixedly connected to the bottom of the connecting hole 41, and the limiting member 51 is larger than the connecting hole 41. By coordinating the positions of the suspension rope 5 and the limiting member 51, the lead plate 4 can be lifted to different positions during the lifting process, thereby allowing multiple lead plates 4 to be arranged into a larger area lead curtain to achieve the function of radiation protection.

[0056] To facilitate the implementation of the suspension rope 2 and the limiting component 51, and to ensure the fixed strength of the limiting component 51, the limiting component 51 is a knot in the suspension rope 2. The position of the knot is fixed, and the position of the lead plate 4 can be fixed and supported by the knot.

[0057] To achieve a seal between adjacent lead plates 4 and fulfill the radiation protection function, the lead plate 4 is divided into: a lower part 401, which mainly provides isolation and radiation protection; an opening 402, which is of a certain width to accommodate the connecting hole 41; and an upper part 403, which seals the connecting hole 41 and also provides some counterweight and support. The lower part 401, the opening 402, and the upper part 403 are integrally formed sequentially from bottom to top, with the connecting hole 41 located in the opening 402. The width of the lower part 401 is greater than the width of the upper part 403. Due to the larger width of the lower part 401, it droops downwards, thereby increasing the area on the vertical surface and improving the radiation protection area. Furthermore, the upper part 403 is bent downwards. The upper part 403 is slightly bent downwards, so that during storage, the upper part 403 can cooperate in the storage process, ensuring that adjacent lead plates 4 can be easily stored together.

[0058] To improve radiation protection, a large-area lead curtain structure is used, with the distance between adjacent knots less than or equal to the width of the lower part 401. This ensures that the width of the lower part 401 of adjacent lead plates 4 is less than the distance between the knots, allowing adjacent lead plates 4 to achieve close isolation between their lower parts 401, forming a lead curtain.

[0059] To facilitate the interaction with the storage rope 6, the pulling device 3 is located at one end of the fixed shell 1. The storage rope 6 passes over the upper side of the pulling device and extends out of the stretching hole 12 along the bottom of the pulling device 3. Through the interaction of the pulling device 3 with the storage rope 6, the position of the lead plate 4 can be adjusted by the limiting effect of the pulling device 3 during the pulling of the storage rope 6.

[0060] To achieve the connection between the pulling device 3 and the fixed shell 1, and also to limit the movement of the storage rope, the pulling device 3 includes: a front plate 31 and a rear plate 32 fixedly connected to the fixed shell 1; a connecting post 3 fixedly connected to the front plate 31 and the rear plate 32; and a rolling post 34 that limits the movement of the storage rope 6, allowing the storage rope 6 to be fixed or released. The front plate 31 and the rear plate 32 are fixedly connected by the connecting post 33, and a sliding groove 35 is formed through the front plate 31 and the rear plate 32. The rolling post 34 is slidably connected through the sliding groove 35, with the upper end of the sliding groove 35 close to the connecting post 33.

[0061] The storage rope 6 wraps around the upper side of the connecting post 33 and extends downward into the tension hole 12 between the rolling post 34 and the connecting post 33.

[0062] The storage rope 6 is wound around the connecting post 33. When the storage rope 6 extending out of the extension hole 12 is pulled and brought close to the rolling post 34, the friction of the storage rope 6 causes the rolling post 34 to roll upward. The rolling post 34 presses the storage rope 6 tightly against the connecting post 33, thereby fixing the position of the storage rope 6 and preventing it from extending, thus achieving the function of storing and fixing the lead plate 4.

[0063] To facilitate the rolling action of the rolling column 34 while also providing stable positioning, the rolling column 34 includes: a column body 341 that primarily achieves the frictional rolling action and a limiting plate 342 that limits the column body 341. The column body 341 passes through the sliding groove 35 of the front plate 31 and the rear plate 32. The limiting plate 342 is fixedly connected to the column body 341 outside the sliding groove 35. The limiting plate 342 extends out of the outer wall of the front and rear plates 32, and by limiting the column body 341, the rolling column 34 can be limited in its sliding motion. This allows the rolling column 34 to slide along the sliding groove 35, to press against the connecting column 33 to tighten the storage rope 6, and to move away from the connecting column 33 to release the storage rope 6.

[0064] Of course, to facilitate the storage of the lead plate 4 by the storage shell 2, the width of the storage shell 2 is greater than or equal to the width of the lead plate 4.

[0065] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
